Close Preview and remain on detail when back selected

I ended up adding a parameter in the url.  This is just so I can properly manipulate the flow, however.  Directly typing in the parameter does not bring up the preview.  Also, after closing the preview, an extra event is left in the forward stack of the history.  However, it is a workable solution.  I'm creating a card to make the preview come up when the url parameter is present.  That will also solve the extra event in the history issue since going forward would then open the preview.
